RBIU

Abbr. for Reciprocal Butt Inspection Unit.

Grounded in Cologne in 2008, the RBIU is well-known as a semi-official (it's recognized in Benelux and Germany, applications for other countries are running) unit that executes inspections on butts. Hereto, several special trained and educated ‘agents’ (although it is said, there is only one agent) either perform inspections by request or at random. If an agent calls upon for an inspection, it can only be refused if a mandate is shown that was handed out by the Chipskonters HQ (q.v.).
